Modify the fields of the Dream custom form as required

The custom form function of Zhimeng allows you to easily create your own form function and collect users' messages, orders, and other information.

However, dedecms user-defined forms have a disadvantage. They do not have a verification function and allow empty forms to be submitted. As a result, the background displays a lot of empty data and cannot collect complete user information. Today, we will add a required content verification function to the dedecms custom form:

1. Modify diy_field_add.htm and add code around 24 lines.

Var necessary = theform. necessary [0]. checked? Theform. necessary [0]. value: theform. necessary [1]. value;

Replace the string, which is about 38 rows.

Replace

Revalue = "<field: "+ fieldname +" itemname = \ "" + itemname + "\" autofield = \ "1 \" type = \ "" + dtype + "\" isnull = \ "" + sisnull + "\" default = \ "" + vdefault + "\"";

Is

Revalue = "<field: "+ fieldname +" itemname = \ "" + itemname + "\" autofield = \ "1 \" type = \ "" + dtype + "\" isnull = \ "" + sisnull + "\" necessary = \ "" + necessary + "\" default = \ "" + vdefault + "\"";

2、diy_field_add.htm, after about 111 lines, add code

                     
 

  

   

    
      Required or not:
Prevent malicious form submission
    
        YesNo
   
  
 

3. Modify diy_field_edit.htm and add code around 18 lines.

Var necessary = theform. necessary [0]. checked? Theform. necessary [0]. value: theform. necessary [1]. value;

Replace the string, which is about 38 rows.

Replace

Revalue + = "isnull = \" "+ sisnull +" \ "default = \" "+ vdefault + "\"";

Is

Revalue + = "isnull = \" "+ sisnull +" \ "necessary = \" "+ necessary +" \ "default = \" "+ vdefault + "\"";

4、diy_field_edit.htm, add code after about 139 lines

             
 

  

   

    
Required or not:
Prevent malicious form submission
    
<Input name = "necessary" type = "radio" value = "true"GetAtt ('cessary') = 'true') echo "checked = '1'";?> Class = 'NP '/> is <input name = "necessary" type = "radio" value = "false"GetAtt ('necessary') = 'false' | $ ctag-> GetAtt ('necessary') = '') echo" checked = '1' ";?> Class = 'NP '/> No
   
  
 

5. Form submission:

Modify the plus/diy. Php file

Find $ addvar = $ addvalue = ''; and add the code above.

// Verify the required field $ row = $ dsql-> GetOne ("SELECT * FROM 'dede _ diyforms 'Where 'table' = '{$ diy-> table }'"); $ fieldset = $ row ['info']; require_once (DEDEINC. "/dedetag. class. php "); $ dtp = new DedeTagParse (); $ dtp-> SetNameSpace (" field "," "); $ dtp-> LoadSource ($ fieldset ); if (is_array ($ dtp-> CTags) {foreach ($ dtp-> CTags as $ tagid => $ ctag) {if ($ ctag-> GetAttribute ("necessary ") = 'true' & empty ($ {$ ctag-> GetName ()}) {show Msg ($ ctag-> GetAttribute ("itemname"). "cannot be blank! ",-1); exit ;}}}

6. This is basically done. Set parameters through the background field editing settings.
 

The above is a required method to modify the fields in the custom form of Zhimeng. I hope it will be helpful to dedecms website construction.
